A realistic model of a simple inkstone used in traditional Chinese calligraphy.
The model is fully UV unwrapped and is low poly, so it is game-ready.There is also a procedural texture in the blend file if the 2k normal map is not high quality enough or you're doing closeups.
note:
For the 2 showcase scenes, I used https://polyhaven.com/a/veranda from HDRI Haven as the HDRI,and https://ambientcg.com/view?id=Wood067 and https://ambientcg.com/view?id=Wood063 from ambientCG as the table and fake pen respectfully.
